Interesting times. Considering the final sentence below, perhaps that simply means Red Hat doesn't have any IP claims against Microsoft, as Novell did...
Microsoft is in an awkward position now that Red Hat has slammed the door shut on any possibility of entering into a patent protection deal similar to the one Redmond has with Novell.
While Microsoft has been telling anyone who will listen that it wants to enter into a similar patent indemnity arrangement with all the other Linux vendors, and is hopeful this will be achieveable with Red Hat, it appears that is not going to happen.
In fact, Mark Webbink, Red Hat's deputy general counsel, told me that "we do not believe there is a need for or basis for the type of relationship defined in the Microsoft-Novell announcement."
